Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Tomatoes Stewed
Ingredients
Directions
Prepare the tomatoes
Pour boiling water over the tomatoes to remove the skins.
Cut the tomatoes into pieces and stew them slowly for 30 minutes.
Season and thicken
Add 1 tablespoon of butter, 1 teaspoon of salt, ¼ teaspoon of pepper, and 1 teaspoon of sugar.
For a sweeter dish, add 2 tablespoons of sugar.
If desired, thicken with 1 tablespoon of flour or corn-starch dissolved in a little cold water.
If desired, thicken with ½ cup of rolled crackers or bread crumbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the dish and release juices that become the stewing liquid.
- Flour or corn-starch
- Thickens the stewing liquid as it heats, giving the sauce body.
- Rolled crackers or bread crumbs
- Absorb liquid and swell, thickening the stewed tomatoes.
The step that matters
Stewing slowly for 30 minutes. Gentle, low heat softens the tomato pieces and lets their juices reduce and blend without scorching. Boiling hard can break the pieces down unevenly and burn the bottom of the pan.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, sugar, flour, bread):
- Capsicumfits better
- Shallotfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, sugar, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
